The ranging device 107 is formed of a Light Detection and Ranging (LiDAR) device, a stereo camera device, or the like, for example, and acquires a space distribution of the distance to a ranging target. Ranging performed by the ranging device 107 may be three-dimensional measurement to measure a distance in the depth direction while scanning two directions of the vertical direction and the horizontal direction, for example. In such a case, the ranging device 107 can acquire three-dimensional information within a range including a salesclerk or a customer. Note that, when the ranging device 107 is formed of a LiDAR device, ranging accuracy in the depth direction can be improved compared to a case where a stereo camera or the like is employed. The type of the laser light source used in the LiDAR device is not particularly limited and may be, for example, a laser light source that emits invisible light such as an infrared ray.

The camera 108 has an area sensor such as a charge coupled device (CCD) sensor or a complementary metal oxide semiconductor (CMOS) sensor and an analog-to-digital conversion circuit, for example.

The drive unit 109 causes the autonomous mobile POS apparatus 10 to move freely under the control of the CPU 101. The audio output unit 110 has a digital-to-analog conversion circuit that converts audio data into an analog signal and an amplifier circuit that amplifies an analog signal and drives a speaker. The audio output unit 110 outputs a sound for preventing collision with a person, a guide voice to a customer, or the like, for example.

The RFID reader/writer 111 performs near field communication with an RFID chip storing a product ID, for example, and receives and outputs the product ID. Once a customer makes payment for a product, the RFID reader/writer 111 writes payment completion information to the RFID chip embedded in a tag of the paid product, for example, under the control of the CPU 101.

The position detection unit 112 transmits a radio intensity from the access point 16 of the shop 18 to a position information calculation server (not illustrated) and acquires position information calculated by the position information calculation server from the position information calculation server, for example. For example, the position information calculation server calculates position information from a radio intensity model measured in advance by using a technique of triangulation. For example, position information acquired by the position detection unit 112 is transmitted to the POS terminal 11, the shop server 12, a salesclerk terminal possessed by a salesclerk, or the like and used for knowing the position of the autonomous mobile POS apparatus 10.

The button 113 is formed of a button used for calling a salesclerk, a button used for causing the autonomous mobile POS apparatus 10 to move, or the like, for example. The code scanner 114 has a CCD sensor or a CMOS sensor, an LED light source, and an analog-to-digital conversion circuit. The CCD sensor or the CMOS sensor may be a line sensor or an area sensor.

The printer 115 has a sheet discharge mechanism for a roll sheet, an ink jet mechanism, and a driver circuit and prints and outputs a receipt or the like. The contactless IC reader/writer 116 acquires credit card information, electronic money information, or the like for payment from a mobile terminal or a contactless IC chip of a medium such as a card possessed by a customer, for example.

The cash drawer 117 stores coins, bills or the like for cash payment and is opened under the control of the CPU 101. The cash drawer 117 is used when a customer makes cash payment via a salesclerk.

The connector 122 is a connector for connecting the autonomous mobile POS apparatus 10 to a battery charger. When the connector 122 is connected to a connector of a battery charger, the autonomous mobile POS apparatus 10 is electrically connected to the battery charger. Note that a connection scheme is not particularly limited, and various schemes can be employed. For example, a connection scheme such that the connector 122 and the connector of a battery charger are formed of contact terminals where contact points corresponding to each other are arranged, these contact terminals are positioned by attractive force of magnets, a three-dimensional shape, or the like to cause contact points corresponding to each other to come into contact with each other, and thereby both the connectors are electrically connected to each other may be employed. Further, for example, a connection scheme such that the connector of the battery charger is formed of a male type, the connector 122 is formed of a female type, and the connector of the battery charger is fit into the connector 122, and thereby both the connectors are electrically connected to each other may be employed.

When the autonomous mobile POS apparatus 10 is connected to a battery charger, the power source unit 120 charges the battery 121 with charging power supply supplied from the battery charger. Further, the power source unit 120 supplies driving power supply supplied from the battery charger to each component of the autonomous mobile POS apparatus 10.

When the autonomous mobile POS apparatus 10 is not connected to a battery charger, the power source unit 120 supplies driving power supply supplied from the battery 121 to each component of the autonomous mobile POS apparatus 10. When the battery level of the battery 121 decreases to a predetermined threshold or lower, the autonomous mobile POS apparatus 10 moves to the standby area 191 where the battery charger is installed. For example, when the autonomous mobile POS apparatus 10 stops at a predetermined charging spot provided in the standby area 191, the connector 122 is connected to the connector of a battery charger, and charging of the battery 121 is automatically performed. Further, when the battery level decreases to a predetermined threshold or lower, the autonomous mobile POS apparatus 10 outputs a warning to a salesclerk or a customer. A warning output method may be, for example, a method of displaying a warning message to the effect that the battery level is the predetermined threshold or lower on the display device 105, a method of outputting the message by voice by using the audio output unit 110, or the like. Note that a salesclerk may connect the autonomous mobile POS apparatus 10 to a battery charger to charge the battery 121. In such a case, the autonomous mobile POS apparatus 10 transmits a warning to the effect that the battery level is a predetermined threshold or lower to the POS terminal 11, the shop server 12, a salesclerk terminal possessed by a salesclerk, or the like, for example, via the wireless communication unit 106. Accordingly, the salesclerk can know that the battery level of the battery 121 is low and promptly have the autonomous mobile POS apparatus 10 charged.

Note that the code scanner 114, the printer 115, the contactless IC reader/writer 116, and the cash drawer 117 may be fixed and provided to the casing of the autonomous mobile POS apparatus 10 or may be detachable from the autonomous mobile POS apparatus 10. When being detachable, these devices may be placed on the placement stage 130, for example.

FIG. 4 is a flowchart illustrating an example of a checkout process using the autonomous mobile POS apparatus 10 according to the present example embodiment.

First, the autonomous mobile POS apparatus 10 is charged in the standby area 191 and stands by in a state of being ready to autonomously move (step S101). When a salesclerk performs a predetermined event, the autonomous mobile POS apparatus 10 detects the event (step S102). The predetermined event may be, for example, performing predetermined movement, pressing a button, inputting a command, or the like. The predetermined movement may be, for example, a gesture such as raising a hand, opening a hand, shaking a hand, or the like. The autonomous mobile POS apparatus 10 specifies a salesclerk who is a tracking target (step S103).

The autonomous mobile POS apparatus 10 tracks the salesclerk while maintaining a constant distance to the salesclerk by using the ranging device 107 (step S104). The constant distance is not particularly limited, which may be any distance so that customer service, work, or the like made by a salesclerk is not obstructed and may be around 2 m, for example. The salesclerk moves in the display area 21 if necessary and serves a customer (step S105). If the served customer purchases a product (step S106, YES), the salesclerk uses the RFID reader/writer 111 to read a tag attached to the product purchased by the customer (step S107). An RFID chip storing the product ID is embedded in the product tag. Note that the autonomous mobile POS apparatus 10 moves closer to the salesclerk based on a predetermined gesture of the salesclerk or the like, for example, and the salesclerk is able to operate the autonomous mobile POS apparatus 10. On the other hand, if the served customer does not purchase a product (step S106, NO), the process returns to step S105.

The autonomous mobile POS apparatus 10 acquires the product ID from the RFID chip embedded in the product tag by using the RFID reader/writer 111 (step S108). Note that, when no RFID chip is embedded in a product tag, the autonomous mobile POS apparatus 10 reads a product code on the product tag by using the code scanner 114 and acquires the product ID, for example. In such a case, the product code may be a one-dimensional barcode or may be a two-dimensional code such as a QR code (registered trademark). The autonomous mobile POS apparatus 10 accesses the shop server 12 via the wireless communication unit 106 (step S109) and acquires product information from a database based on the product ID (step S110). The autonomous mobile POS apparatus 10 displays checkout information such as a product name, a price, or the like on the display device 105 (step S111). The customer makes payment by using the autonomous mobile POS apparatus 10 in the display area 21 based on the checkout information displayed on the display device 105 (step S112). The autonomous mobile POS apparatus 10 writes the payment completion information to the RFID chip embedded in the product tag by using the RFID reader/writer 111 (step S113). Thereby, it is possible to distinguish a paid product and an unpaid product. For example, it is possible to prevent an unpaid product from being brought out of a shop by installing gates that can read RFID chip information at the entrance and the exit of the shop 18 and outputting a warning sound or the like when an unpaid product is brought out of the shop.

Note that the checkout process for a service is performed based on a medium in which an RFID chip storing a service ID is embedded, for example. The service ID is information for specifying a service. The medium may be, for example, a sheet, a card, a plate, or the like. After a customer makes payment for a service, the autonomous mobile POS apparatus 10 writes payment completion information to the RFID chip embedded in the medium of the paid service by using the RFID reader/writer 111. Thereby, it is possible to distinguish a paid service and an unpaid service.

FIG. 5 is a flowchart illustrating an example of a process using the autonomous mobile POS apparatus 10 according to the present example embodiment.

First, the autonomous mobile POS apparatus 10 is charged in the standby area 191 and stands by in a state of being ready to autonomously move (step S201). The autonomous mobile POS apparatus 10 acquires image information on the display area 21 and information that specifies a captured area in the display area 21 from the network camera 15 via the wireless communication unit 106 (step S202). The autonomous mobile POS apparatus 10 calculates a people distribution density in the display area 21 based on the image information (step S203).

The autonomous mobile POS apparatus 10 determines whether or not the people distribution density exceeds a predetermined threshold (step S204). If it is determined that the people distribution density exceeds the predetermined threshold (step S204, YES), the autonomous mobile POS apparatus 10 determines a target place to move in the display area 21 (step S205). The target place to move may be, for example, a captured area where the people distribution density exceeds a predetermined threshold, a place near such a captured area, or the like. That is, the autonomous mobile POS apparatus 10 moves to a place where customers are concentrated in the display area 21. Accordingly, the customer can make payment by using the autonomous mobile POS apparatus 10 in the display area 21 without moving to the register area 20 from a crowded place. On the other hand, if it is determined that the people distribution density does not exceed the predetermined threshold (step S204, NO), the process returns to step S202.

The autonomous mobile POS apparatus 10 determines whether or not a help request notification is set to be transmitted to a salesclerk terminal possessed by a salesclerk (step S206). The help request notification includes information related to a target place to move. If it is determined that a help request notification is set to be transmitted (step S206, YES), the autonomous mobile POS apparatus 10 transmits a help request notification to a salesclerk terminal (step S207). On the other hand, if it is determined that a help request notification is not set to be transmitted (step S206, NO), the process proceeds to step S208.

The autonomous mobile POS apparatus 10 starts moving (step S208) and reaches a target place to move in the display area 21 (step S209). The autonomous mobile POS apparatus 10 determines whether or not there is a response from the salesclerk terminal (step S210). If it is determined that there is a response from the salesclerk terminal (step S210, YES), the autonomous mobile POS apparatus 10 stands by in the display area 21 (step S211). The salesclerk reaches the target place to move and serves the customer (step S212). If the customer purchases a product, the salesclerk performs reading of a product tag by using the autonomous mobile POS apparatus 10 or the like, and the customer makes payment by using the autonomous mobile POS apparatus 10 in the display area 21 (step S213).

If it is determined that there is no response from the salesclerk terminal (step S210, NO), the autonomous mobile POS apparatus 10 outputs an announce to the customer by using the audio output unit 110 (step S214). The case where there is no response from the salesclerk terminal may be, for example, a case where a salesclerk who noticed the help request notification is unable to respond because of serving another customer or the like, a case where setting to perform a help request is disabled, or the like. The announce message may be, for example, a message such as “Please push clerk call button if you need clerk's assistance”, a message related to an advertisement for a product or a service, or the like. Note that such a message may be displayed on the display device 105. If a customer pushes a salesclerk call button (step S215, YES), the process proceeds to step S212. In such a case, the autonomous mobile POS apparatus 10 transmits position information acquired by the position detection unit 112 to the POS terminal 11, the shop server 12, a salesclerk terminal possessed by a salesclerk, or the like together with the salesclerk call notification. Accordingly, the salesclerk is able to promptly move to the place of the customer who pushed the salesclerk call button and serve the customer. On the other hand, if the customer does not push the salesclerk call button (step S215, NO), the customer makes payment by using the autonomous mobile POS apparatus 10 in the display area 21 based on guidance as to how to use a self-service register displayed on the display device 105 or the like (step S216). The guidance may be, for example, guidance as to how to have a product tag read, have an IC card read in electronic payment, supply a coin and input a bill in cash payment, or the like. In such a way, a customer can select whether or not to call a salesclerk by using the autonomous mobile POS apparatus 10. Note that a customer may call a salesclerk by performing a predetermined gesture, inputting a command, or the like, for example.

Note that, if it is determined that the people distribution density exceeds a predetermined threshold, the autonomous mobile POS apparatus 10 may determine a motion path and a target place to move so as to avoid a place where customers are concentrated, for example. In such a case, the autonomous mobile POS apparatus 10 avoids a crowded place and moves to a place where customers are not concentrated. Accordingly, a customer is able to make payment by using the autonomous mobile POS apparatus 10 in an uncrowded place while the autonomous mobile POS apparatus 10 does not obstruct customer's shopping. It is desirable that the threshold in such a case be higher than the threshold in step S204. In such a way, by using a plurality of different thresholds, it is possible to move the autonomous mobile POS apparatus 10 to a place suitable for a checkout process. Note that the autonomous mobile POS apparatus 10 may output a voice announce or the like after reaching the target place to move and let a customer to know a position of the autonomous mobile POS apparatus 10.

Further, based on the usage status of an autonomous mobile POS apparatus 10A, a target place to move may be determined for another autonomous mobile POS apparatus 10B. For example, a case where the autonomous mobile POS apparatus 10A has already moved to a predetermined place in the display area 21 and is used by a salesclerk or a customer is assumed. When the people distribution density in a predetermined place of the display area 21 is high, another autonomous mobile POS apparatus 10B may be caused to move closer to the predetermined place. By arranging another autonomous mobile POS apparatus 10B near the predetermined place, the customer is able to make payment by using the autonomous mobile POS apparatus 10 in the display area 21 without moving to the register area 20 from the crowded place.

Although a case of calculating a people distribution density to determine a target place to which the autonomous mobile POS apparatus 10 moves has been described in FIG. 5, the example embodiment is not limited thereto. For example, a target place to which the autonomous mobile POS apparatus 10 moves may be determined based on positions of a plurality of persons. Further, when more persons than the threshold are present in a predetermined place in the shop, the predetermined place or a place nearby may be determined as a target place to which the autonomous mobile POS apparatus 10 moves.

As described above, in the present example embodiment, a customer makes payment by using the autonomous mobile POS apparatus 10 in the display area 21 without limited to the register area 20. Thus, according to the present example embodiment, it is possible to perform a smooth checkout process.

Second Example Embodiment

The second example embodiment of the present invention will be described with reference to FIG. 6. The same components as those in the first example embodiment are labeled with the same references, and the description thereof will be omitted or simplified.

The present example embodiment assumes a case where the autonomous mobile POS apparatus 10 moves on a predetermined path based on induction current from an electric wire installed in a floor, a magnetic tape or a marker attached on a floor, or the like, for example, in the same manner as an automated guided vehicle (AGV). The autonomous mobile POS apparatus 10 moves based on a schedule pre-registered by a salesclerk. The schedule includes time to start moving, a motion path, a target place to move, a standby period at a target place to move, or the like, for example. A customer uses the autonomous mobile POS apparatus 10 as a self-service register, and gates that can read RFID chip information are installed at the entrance and the exit of the shop 18.

FIG. 6 is a flowchart illustrating an example of a checkout process using the autonomous mobile POS apparatus 10 according to the present example embodiment.

First, the autonomous mobile POS apparatus 10 is charged in the standby area 191 and stands by in a state of being ready to autonomously move (step S301). The autonomous mobile POS apparatus 10 confirms a pre-registered schedule (step S302) and determines whether or not the current time is the time to start moving (step S303). If it is determined that the current time is the time to start moving (step S303, YES), the autonomous mobile POS apparatus 10 moves on a predetermined path based on a registered schedule (step S304). On the other hand, if it is determined that the current time is not the time to start moving (step S303, NO), the process returns to step S302.

The autonomous mobile POS apparatus 10 reaches a target place to move registered in the schedule (step S305). If a customer purchases a product (step S306, YES), the customer uses the RFID reader/writer 111 to read a tag attached to the product to be purchased based on guidance as to how to use a self-service register displayed on the display device 105 or the like (step S307). The guidance may be, for example, guidance as to how to have a product tag read, have an IC card read in electronic payment, supply a coin and input a bill in cash payment, or the like. On the other hand, if the customer does not purchase a product (step S306, NO), the process proceeds to step S314.

The autonomous mobile POS apparatus 10 acquires the product ID from an RFID chip embedded in a product tag by using the RFID reader/writer 111 (step S308). The autonomous mobile POS apparatus 10 accesses the shop server 12 via the wireless communication unit 106 (step S309) and acquires product information from a database based on the product ID (step S310). The autonomous mobile POS apparatus 10 displays checkout information such as the product name, the price, or the like on the display device 105 (step S311). The customer makes payment by using the autonomous mobile POS apparatus 10 in the display area 21 based on the checkout information displayed on the display device 105 (step S312). The autonomous mobile POS apparatus 10 writes payment completion information to the RFID chip embedded in the product tag by using the RFID reader/writer 111 (step S313). Since gates that can read RFID chip information are installed at the entrance and the exit of the shop 18, if a customer brings an unpaid product out of the shop, a warning sound or the like are output, for example. Accordingly, it is possible to prevent an unpaid product from being brought out of the shop.

The autonomous mobile POS apparatus 10 determines whether or not elapsed time after reaching the target place to move exceeds a standby period registered in the schedule (step S314). If it is determined that the elapsed time exceeds the standby period (step S314, YES), the autonomous mobile POS apparatus 10 moves to the standby area 191 (step S315). On the other hand, it is determined that the elapsed time does not exceed the standby period (step S314, NO), the process returns to step S306.

As described above, in the present example embodiment, a customer makes payment by using the autonomous mobile POS apparatus 10 without intervention of a salesclerk in the display area 21 without limited to the register area 20. Thus, according to the present example embodiment, it is possible to perform a smooth checkout process.

Third Example Embodiment

The third example embodiment of the present invention will be described with reference to FIG. 7. The same components as those in the first example embodiment and the second example embodiment are labeled with the same references, and the description thereof will be omitted or simplified.

In the present example embodiment, a case where the shop 18 is an unmanned shop is assumed. The autonomous mobile POS apparatus 10 functions as a robot that serves a customer by interaction or the like, for example. An entry gate is installed at the entrance of the shop 18, and an exit gate that can read RFID chip information is installed at the exit of the shop 18. Each of the entry gate and the exit gate may be formed of flapper type gates having two flaps, for example, but may be formed using one flap.

FIG. 7 is a flowchart illustrating an example of a checkout process using the autonomous mobile POS apparatus 10 according to the present example embodiment.

First, when a customer visits the shop 18 and stands in front of the entry gate (step S401), the entry gate is opened (step S402). When the customer performs a predetermined event, the autonomous mobile POS apparatus 10 detects the event (step S403). The predetermined event may be, for example, performing predetermined movement, pressing a button, inputting a command, or the like. The predetermined movement may be, for example, a gesture such as raising a hand, opening a hand, shaking a hand, or the like. The autonomous mobile POS apparatus 10 specifies the customer who is a tracking target (step S404).

The autonomous mobile POS apparatus 10 tracks the customer while maintaining a constant distance to the customer by using the ranging device 107 (step S405). The constant distance is not particularly limited, which may be any distance so that shopping made by a customer is not obstructed and may be around 2 m, for example. The customer selects a product to be purchased (step S406) and uses the RFID reader/writer 111 to read a tag attached to the product to be purchased based on guidance as to how to use a self-service register displayed on the display device 105 (step S407). The guidance may be, for example, guidance as to how to have a product tag read, have an IC card read in electronic payment, supply a coin and input a bill in cash payment, or the like. Note that the autonomous mobile POS apparatus 10 may move closer to the customer based on a predetermined gesture or the like of the customer, and the customer may operate the autonomous mobile POS apparatus 10, for example. The autonomous mobile POS apparatus 10 acquires the product ID from an RFID chip embedded in a product tag by using the RFID reader/writer 111 (step S408). The autonomous mobile POS apparatus 10 accesses the shop server 12 via the wireless communication unit 106 (step S409) and acquires product information from a database based on the product ID (step S410). The autonomous mobile POS apparatus 10 displays payment information such as the product name, the price, or the like on the display device 105 (step S411). The customer makes payment by using the autonomous mobile POS apparatus 10 in the display area 21 based on the payment information displayed on the display device 105 (step S412). The autonomous mobile POS apparatus 10 writes payment completion information to the RFID chip embedded in the product tag by using the RFID reader/writer 111 (step S413). Thereby, it is possible to distinguish a paid product and an unpaid product. Note that the autonomous mobile POS apparatus 10 moves to a predetermined standby place after the checkout process.

The customer packs the product and moves to the front of the exit gate (step S414). If there is no unpaid product in the packed product (step S415, NO), the exit gate is opened (step S416), and the customer can exit the shop 18 (step S417). On the other hand, if there is an unpaid product in the packed product (step S415, YES), for example, a warning sound or the like are output (step S418), the exit gate is not opened, and the customer is unable to exit the shop 18 (step S419). Accordingly, it is possible to prevent an unpaid product from being brought out of the shop.

As described above, in the present example embodiment, a customer makes payment by using the autonomous mobile POS apparatus 10 in the display area 21 without limited to the self-service register area, for example, in an unmanned shop. Thus, according to the present example embodiment, it is possible to perform a smooth checkout process.

Fourth Example Embodiment

The fourth example embodiment of the present invention will be described with reference to FIG. 8.

FIG. 8 is a block diagram of an information processing apparatus 30 according to the present example embodiment. The information processing apparatus 30 has a motion unit 40 that performs a checkout process for a product or a service and causes the information processing apparatus 30 to autonomously move, a detection unit 50 that can detect a position of a person, and a control unit 60 that controls the motion unit 40 in accordance with the position of the person. According to such a configuration, a customer is able to make payment by using the information processing apparatus 30 that autonomously moves in a display area without limited to a register area. Thus, according to the present example embodiment, it is possible to perform a smooth checkout process.

Other Example Embodiments

The present invention is not limited to the example embodiments described above and can be changed as appropriate within a scope without departing from the spirit of the present invention.

Although the case where the autonomous mobile POS apparatus 10 calculates a people distribution density based on image information acquired by the network camera 15 to determine a target place to move has been described in the above example embodiments, the example embodiment is not limited thereto. For example, information related to a people distribution within a shop may be acquired by using the ranging device 107 to determine a target place to move. Further, a target place to move may be determined based on image information acquired by the camera 108. In such a case, the autonomous mobile POS apparatus 10 has a face authentication function, matches pre-registered face image data of salesclerks with a face included in an image acquired by the camera 108, and distinguishes whether the person captured by the camera 108 is a salesclerk or a customer. Thereby, the autonomous mobile POS apparatus 10 is able to move a place where many customers and few salesclerks are present, for example. Note that, when the autonomous mobile POS apparatus 10 has a face authentication function, a payment method may be face authentication payment. In such a case, the autonomous mobile POS apparatus 10 matches pre-registered face image data of customers with a face included in an image captured by the camera 108 to perform identity verification. If the identity verification is successful, payment is performed based on credit card information on a customer registered in association with the face image data, for example.

Further, although the case where the standby place of the autonomous mobile POS apparatus 10 is the standby area 191 has been described in the above example embodiments, the present invention is not limited thereto. The standby place may be any place where customer service or work made by a salesclerk, shopping made by a customer, motion of a person, or the like are not obstructed and may be an empty space of the register area 20 or the display area 21 or the like, for example.

Further, although the case where the charging place of the autonomous mobile POS apparatus 10 is the standby area 191 has been described in the above example embodiments, the present invention is not limited thereto. The charging place may be any place where a battery charger can be installed and where customer service or work made by a salesclerk, shopping made by a customer, motion of a person, or the like are not obstructed and may be an empty space of the register area 20 or the display area 21 or the like, for example.

Further, the scope of each of the example embodiments includes a processing method that stores, in a storage medium, a program that causes the configuration of each of the example embodiments to operate so as to implement the function of each of the example embodiments described above, reads the program stored in the storage medium as a code, and executes the program in a computer.
